The event, which aired via online pay-per-view, took place at the Sydney Entertainment Centre in Sydney, New South Wales, Australia.

Rizzo (19-9), picking up his third straight win, cut down Shamrock (27-14-2) with kicks to his left leg. Once Shamrock hit the mat a little more than three minutes into the fight, Rizzo followed up with ground and pound to force the referee’s intervention and a TKO stoppage at the 3:33 mark.

Daley (24-9-2), meanwhile, fought for the first time since a post-loss punch to opponent Josh Koscheck that prompted his UFC release. Facing PRIDE vet Daniel Acacio (21-10) in the night’s co-headliner, Daley endured two fairly even rounds before his opponent pulled guard in the third. Once on the mat, Daley unloaded a vicious elbow strike that opened a deep gash on Acacio’s forehead that prompted the welterweight fighter to submit verbally.

Palelei (11-2), meanwhile, fought for just the second time since a 2007 loss to Eddie Sanchez at UFC 79. After fending off fellow ex-UFC heavyweight Brad Morris (10-5) and his takedown attempts, Palelei used knees and punches to force him to the mat, where he secured a fight-ending keylock in the final minute of the fight.

In a highly anticipated middleweight bout initially slated for PRIDE’s 2006 middleweight grand prix (but scratched due to injury), former WEC champ Paulo Filho (20-1-1) and recent UFC fighter Denis Kang (33-12-2) fought to an eventual split draw. The mostly grappling affair resulted in no clear-cut winner, which was reflected in the range of scores. (One judge had it 29-28 for Filho, one had it 30-27 for Kang, and the third had it 29-29.) Although plagued with personal problems that have slowed his career, Filho failed to garner a win for just the second time in 22 pro fights.

In a bout likely to garner him some attention from the major promotions, first-ever EliteXC middleweight champ “Ninja” Rua picked up his fourth straight win with a first-round guillotine choke of “The Ultimate Fighter 7” cast member Jeremy May (7-7). Rua, who is the brother of UFC champ Mauricio “Shogun” Rua, now has posted stoppages in his past 11 wins going back to 2002.

In the preceding middleweight bout, “TUF 7” finalist Taylor (15-6) benefited from his opponent’s bad luck and snapped out of a 1-3 skid. In a wrestler vs. grappler fight, Taylor’s wrestling gave him a slight edge over former UFC champ Murilo Bustamante (14-8-1). But the bout came to a premature end in the second round when Bustamante waved off the fight due to apparent dizziness, which gave Taylor the dubious win.
